Platform engineering: what is it and why do you need it?

Platform engineering is a crucial aspect of modern DevOps aimed at reducing the cognitive load on developers by facilitating seamless software interaction and delivery. Platform Engineers, often referred to as the MacGyvers of DevOps, play a vital role in managing an Internal Developer Platform (IDP), which serves as a self-service layer between developers and the underlying infrastructure. This role is essential in helping developers navigate complex environments, deploy new features, and maintain service quality and security, thus enhancing the overall Developer Experience (DevEx). The IDP aims to streamline the development lifecycle by providing a unified platform for managing services, cloud resources, and third-party tools, ultimately enabling faster onboarding, improved incident resolution, and adaptive governance. Platform Engineers, distinct from Site Reliability Engineers (SREs), focus on building and maintaining these platforms to ensure agility and innovation without compromising governance and control, making them indispensable in the software modernization journey.
